Stone aggregates are one of the most important construction materials obtained through conventional mining and crushing of building stones. The construction mining sector is highly unorganized, despite alarm calls raised by individuals and corporates regarding high accident rates and rapidly declining stone deposits. We may soon run out of quality stone deposits to support our aspiring infrastructure development plans. This article aims to create awareness on the importance of stone quarrying in supporting our infrastructure development plans, challenges faced by this sector, and eliciting appropriate and concrete action plans for the future.Keywords

The energy produced by solar photovoltaic (SPV) modules is directly connected with the solar accessible irradiance, spectral content, different variables like environmental and climatic components. Dust and bird droppings are considered as the real challenges for SPV performance. This article covers dust-related challenges and advanced improvements made on the automated cleaning system, by providing a brief framework on strategies such as mechanical, electrical, chemical and electrostatic. The environmental impact of cleaning processes has also been evaluated, which is directly related to the ultimate performance of overall conversion.Keywords

PepMoV was first recognized in Arizona (USA) in 1969 as a new strain of potyvirus that infected peppers. It was first reported from Palm Beach County, Delray Beach, Florida, (USA)1–3 in Capsicum annuum. Recently, the virus has been reported from other pepper growing countries of the world, such as Taiwan, India, Korea, China, Japan, Cuba4–9. Indian chilli (Capsicum annuum) is infected by potyviruses such as Potato virus Y (PVY) and Pepper veinal mottle virus10,11.Full Text

Crushed stone aggregates are indispensable construction material which is produced by crushing of raw stone boulders raised from stone quarries through the process of drilling and blasting. Proper size of boulders fed to the crusher is important to eliminate congestion in the crushing circuit and obtaining the desired productivity. Drill-blast design parameters have a considerable effect on the degree of post-blast fragmentation. Bench height, spacing, burden, stemming, bench stiffness ratio and powder factor are controllable blast design parameters which considerably influence the fragmentation. By controlling these design parameters, optimum fragmentation can be achieved. Extensive field trials followed by scientific analysis have been done in this study which reveals the relation between drill-blast design parameters and post-blast fragmentation. Burden, spacing, stemming, bench stiffness ratio and powder factor were varied over a range of 30–45% which in turn caused distinctions in the mean fragment size in the range of 50–200% approximately. For optimum mean fragment size, the burden was found to be 21 times the blast hole diameter. Spacing dimension of 1.3 times the burden produced the optimum mean fragment size. Stemming length of 0.91 times of burden generated the optimum fragmentation. Mean fragment size was most optimum at powder factor of 1.02 kg/cum.Keywords
